1、使用特效散点图实现产品出货TOP5显示；
2、实现自定义悬浮提示框；
如下图所示：
实现步骤
一、在vue中安装echarts
npm install echarts
二、在vue组件中使用echarts
1、在组件中先引入echarts；
import echarts from 'echarts' // 引入echarts中国地图数据
2、在组件中引入中国地图数据；
require('echarts/map/js/china');
提示：地图类的echarts实现是需要额外引入地图数据。
见官网：https://echarts.baidu.com/option.html#geo.map
3、在组件页面内定一个标签来渲染地图；
<div id="productMap" style='width:600px;height:500px;'></div>
4、初始化 echarts 实例和指定配置参数；
var vm = new Vue({
el: '#productMap',
data: {
name_title: "全国各省产品销量图",
subname: '',
nameColor: "rgb(33, 75, 113)",
name_fontFamily: '等线',
subname_fontSize: 15,
name_fontSize = 18,
max: 480,
min: 9; // todo
maxSize4Pin: 100,//散点图最大尺寸
minSize4Pin: 20;//散点图最小尺寸
mapName: 'china',
geoCoordMap: {},
chinaChart: echarts.init(document.getElementById('productMap'));// 初始化echarts实例
},
methods: {
getGeoCoordMap: function () {
/*获取地图数据*/
let mapFeatures = echarts.getMap(this.mapName).geoJson.features;
this.chinaChart.hideLoading();
mapFeatures.forEach(function(v) {
// 地区名称
let name = v.properties.name;
// 地区经纬度
geoCoordMap[name] = v.properties.cp;
});
return this.geoCoordMap;
},
convertData: function(data) {
let res = [];
for (let i = 0; i < data.length; i++) {
var geoCoord = this.geoCoordMap[data[i].name];
if (geoCoord) {
res.push({
name: data[i].name,
value: geoCoord.concat(data[i].value),
});
}
}
return res;
},
getData: function(){
//数据从接口中获取，格式：
/*
data = [
{
name: "北京",
value: 177
},
...
]
*/
return data;
},
getToolTipData: function(){
//数据从接口中获取
let data = this.getData();
let toolTipData = {};
//通过解析data，返回toolTipData数据
//格式：
/*
data = [[{
name: "北京",
value: [
{
name: "主机",
value: 95
}, {
name: "监控卡",
value: 82
}]
},
...
];
*/
return toolTipData;
}
},
mounted () {挂载完毕后进行初始化地图数据
this.chinaChart.showLoading();
// 进行相关配置
this.chartOption = {
